Journal ArticleDOI

Non-racemic amino acid production by ultraviolet irradiation of achiral interstellar ice analogs with circularly polarized light

Pierre de Marcellus, +8 more
- 01 Feb 2011 - 
TL;DR: In this paper, the first abiotic cosmic ice simulation experiments that produce species with enantiomeric excesses (e.g., 1.34% for (13C)-alanine) were reported.
Journal ArticleDOI

Structural and chemical alteration of crystalline olivine under low energy He + irradiation

Karine Demyk, +8 more
- 01 Mar 2001 - 
TL;DR: In this paper, the results of irradiation experiments on crystalline olivine with He + ions at energies of 4 and 10 keV and fluences varying from 5 10 16 to 10 18 ions/cm 2.
Journal ArticleDOI

Low-energy helium ion irradiation-induced amorphization and chemical changes in olivine: Insights for silicate dust evolution in the interstellar medium

Philippe Carrez, +7 more
- 01 Nov 2002 - 
TL;DR: In this paper, the results of irradiation experiments aimed at understanding the structural and chemical evolution of silicate grains in the interstellar medium (ISM) were presented, where the energies and fluences of the helium ions used in this study were chosen to simulate the irradiation of interstellar dust grains in supernovae shock waves.
Journal ArticleDOI

A detailed study of the amino acids produced from the vacuum UV irradiation of interstellar ice analogs.

Michel Nuevo, +3 more
- 04 Jan 2008 - 
TL;DR: The amino acids were detected and identified by ex-situ liquid chromatography analysis of the organic residues formed after warming the photolysed ices up to room temperature, showing that in all experiments amino acids are formed.
Journal ArticleDOI

Aldehydes and sugars from evolved precometary ice analogs: Importance of ices in astrochemical and prebiotic evolution

Pierre de Marcellus, +6 more
- 27 Jan 2015 - 
TL;DR: The importance of detecting aldehydes and sugars in extraterrestrial environments, in the gas phase of hot molecular clouds, and, more importantly, in comets and in primitive meteorites that have most probably seeded the Earth with organic material as early as 4.2 billion years ago is pointed out.
